<div>Well, we just had a discussion on the list about my choppy play back using FC5 and a VIA Graphics card, I solved the problem with:</div>
<div> </div>
<div>edit /etc/grub.conf<br>and modify your kernel line adding to the end:</div>
<div> </div>
<div>noapic nolapic pci=noacpi acpi=off</div>
<p> </p>
<div> </div>
<div>Try it, you never know.</div>

<br>problems are common for some MythTV users, and I am<br>using MythTV as my GUI. I'm having problems with<br>video playback on my machine.<br><br>To start, here's my equipment:<br><br>Processor:P3 866<br>Mobo: Gigabyte GA-6PMM
<br>Memory: 256MB PC133<br>Video Card: Guillemot 3D Prophet II GeForce2 GTS 64MB<br>HD: 300GB Seagate Ultra-ATA<br>DVD: Some LG type, can't remember exactly.<br><br>This system is not a PVR. It may become a PVR type<br>system later, but for now it doesn't have a TV card in
<br>it. All I want to do is play videos that I FTP to it,<br>play DVDs, and maybe get into some MAME action too<br>later on. But most importantly, it must play videos.<br><br><br>The problem I'm having is that the video jerks about
<br>once a second. This happens on all video: DVDs, DivX,<br>MPEGs, everything. The player doesn't make a<br>difference: I've tried Mplayer, VLC, and Xine, all<br>with the same exact result. It doesn't seem to matter<br>
what distro I try: Fedora Core 4 and Kubuntu gave the<br>same result. Under Win2K however, video playback is<br>perfect with VLC and Windows Media Player so the<br>hardware should be OK. It's not the sound, because<br>
using Mplayer with -nosound gave the same result.<br>Video drivers don't seem to make a difference: using<br>the open-source nv drivers and using nVidia's drivers<br>gives the same result. It's not the DMA settings:<br>both the HD and the DVD have DMA on. Dropping the AGP
<br>settings to 2X instead of 4X in the BIOS did nothing.<br>Doing the "echo 1024 > /proc/....I can't remember the<br>rest off hand" had no effect. Turning off double<br>buffering with xvattr doesn't seem to do anything.
<br>It's not the video processor (I think that's what it's<br>called anyways): using xv is the best, but still<br>chops. Using gl, x11, or any others makes things<br>worse. It's not the processor being overworked:<br>looking at CPU usage with top, it's using 20% at the
<br>most during playback. The type of partition doesn't<br>seem to matter: both ext3 and jfs give the same<br>result. It's definately not the memory, since it had<br>PC100 in it before but I decided to buy PC133 to see<br>
if it would help. It didn't. And yes, I did set the<br>memory speed in the BIOS as well after upgrading.<br><br>I can't remember everything I've tried, but the only<br>thing that seems to help is adding Option "NvAPG" "1"
<br>to my xorg.conf. The jerk is still there, but at<br>least the video is somewhat watchable. I can't find<br>anything else to try by searching online, or think of<br>any other reasons why this is happening. If anyone
<br>can help me out, I would really appreciate it. I want<br>my media box...<br><br>Thanks<br>Brent<br><br><br><br>___________________________________________________________<br>The all-new Yahoo! Mail goes wherever you go - free your email address from your Internet provider.
